Winchester Primers

Winchester primers is the largest manufacturer of small caliber ammunition for the U.S. military. Proven in battle for more than 100 years, we’ve delivered trusted ammunition products for civilians, law enforcement and military. With the addition of the Lake City Army Ammunition Plant, we’re proudly bolstering our commitment to support the modern Warfighter by designing and producing the highest-quality ammunition products.

Non-corrosive, all weather primers deliver fast, dependable ignition under any shooting condition. Winchester works to make sure all primers are reliable, instant and precise. In Winchester testing labs, primers are constantly and rigorously tested for consistency and sensitivity at temperatures and conditions far beyond the range of normal usage. Winchester guarantees better sensitivity for more positive firing in all guns, carefully-controlled weights of primer mixtures, consistency in size and quality, precise measurements and tolerances for anvil heights, and stability in extremes of temperatures and humidity.
